Description

Black Jade Granite is a melanocratic rock with a dark grey tint, featuring scattered black crystals of centimeter size. The granite exhibits a granular, phaneritic texture with a fine to medium grain. Constituent minerals generally appear as grains with an euhedral to subhedral shape, some displaying a prismatic tendency, and the rock is devoid of lineation, cracks, pores, or cavities. Notably, the rock does not exhibit any form of orientation, foliation, schist, or apparent tectonic deformation.

This intrusive (plutonic) igneous rock originates from the Province of Huila, located in the south of Angola. It is primarily composed of non-equidimensional grains of pyroxenes and plagioclases, presenting a holocrystalline texture. The phaneritic nature of the granite is characterized by a non-equigranular structure with a medium to coarse grain size, displaying a hip idiomorphic tendency. The absence of apparent deformation features contributes to the distinctive aesthetic and durability of Black Jade Granite, making it a sought-after material for various design applications such as countertops, flooring, and wall cladding.
